Thanks to Block Scientific, I was able to procure the re-certified Bayer DCA 2000+ without hassles and get the lab back in operation. The
device works perfectly and I look forward to doing more business with Block Scientific.

Aspergillus fumigatus IgM ELISA, 96 wells

INTENDED USE

Enzyme immunoassays for the qualitative and quantitative determination of IgM antibodies against Aspergillus fumigatus in human serum and plasma.

SUMMARY

The most common pathogen of the genus Aspergillus is A. fumingatus occuring in hay, grain, rotten plants and bird faeces. The main opportunistic invasive fungal infections are the candidal mycosis followed by aspergillosis. In general infections with Aspergillus spp. are airborne. Because of the ubiquity of Aspergillus species it is difficult to decide between contamination by commensalism or a serious infection. Usually infection in humans occurs in already damaged
tissues only. Aspergillus spp. can cause a chronic infection of paranasal sinus, eyes or lungs.
Three types of lung-aspergillosis can be distinguished: acute infection (bronchial pneumonia; pneumonia), saprophytic aspergillom (compact reticulum of hyphae in the lungs) and allergic bronchopulmonal aspergillosis (mediated by IgE).

Next to the ELISA the indirect Aspergillus hemagglutination test (Aspergillus HAT) can be performed to detect specific IgG and IgM antibodies. The HAT is not suitable as a screening test, however, because of its low sensitivity. In some high-risk patients it shows only low antibody titers.
